A copolymer useful for hydrophobically reforming a porous fluoropolymer support is disclosed. Examples of such copolymers are the following: . Also disclosed are a process for producing such a copolymer, a method for modifying the surface of a porous fluoropolymer, and a hydrophilic fluoropolymer porous membrane prepared therefrom. A filtration method of a fluid using the hydrophilic fluoropolymer porous membrane is also disclosed. |
